Sulfate, Quant, 24-Hour Urine

24-hour urine sulfate quantifies total sulfate excretion, reflecting dietary intake (mainly from sulfur-containing amino acids like methionine and cysteine) and metabolic sulfation capacity. It's used to assess nutritional status, evaluate detoxification capacity, and screen for rare metabolic or kidney disorders.

Not especially athlete-specific. Sulfate excretion doesn't directly track training load, recovery, or performance. Some biohackers monitor it as a proxy for antioxidant status or sulfation detoxification capacity under heavy training stress, but clinical evidence supporting this practice in athletes is limited. Standard markers like cortisol, creatine kinase, and heart-rate variability remain more evidence-based for training recovery.
